BLOW P IPE.

SPECIFICATION forming part of Letters Patent N0. 601,208, dated. March22, 1898.

Application filed September 11, 1897. Serial No. 651,332. (No model.)

To all whom/it mdy concern:

Be it known that I, CHARLES H. KING, of

'new and Improved Blowpipe, of which the following is a full, clear, and"exact description. v

This invention relates to improvements in blowpipes; andthe object is toprovide a device of this character that will blow a .very strong "heatwithout blackening the metal being soldered or otherwise treated, and,fur ther, to provide a blowpipe that will be comparatively cheap tomanufacture.

I will describe a blowpipe embodying my invention, and then point outthe novel features in the appended claim.

. Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a perspective view of a blowpipe embodying my invention, andFig. 2- is a vertical section thereof.

Referring to the drawings, 1 designates a boiler supported by andadjustable vertically on a standard 2, mounted on a base-plate or tray3. The boiler has a plug-closed fillinghole in its top, and from theupper portion of the boiler a tube 4 extends upward and providescommunication between the interior of A blowpipe 6 extends into thecondensing-cylinder 5,,and, as will be. seen in Fig. '2, the end of theblowpipe within the cylinder extends nearly to the top thereof andconsiderably above the inlet of the tube 4:, so that moisture resultingfrom condensation will be prevented from entering the pipe 6 andmingling with the flame.

Underneath the boiler l'is a heating-lamp 7 for heating the liquid inthe boiler, and arranged adjacent to the outlet of the pipe 6 is aflame-lamp 8. In connection with'the device I may employ a hood 9, inwhich the lamp 8 will be placed. This hood is open at one end and at thetop, and it has a deflectorplate 10 in line with the outlet of the tube6. When in use, the flame forced against the plate 10 will reboundagainst the sides of the hood and thus economize the heat-to be appliedto any article placed on the open top of the hood.

Preferably I will use alcohol in the lamps and also in the boiler, as itis well known that an alcohol-flame will not blacken articles subjectedto it.

In use I generally half-fill the boiler, and when the alcohol shall havereached the boiling-point the pressure will cause a strong blast throughthe blowpipe, and for additional safety I provide the boiler with asafety-valve 11, which may be of any desired construction. If desired,the blowpipe 6 may be made to rotate at the bulb 12, so as to direct theflame as required.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A blowpipe, comprising a boiler, a heatinglamp, ablowpipe communicating with the boiler, a flame-lamp, a tray on whichthe lamps are mounted, a hood mounted on the tray and tor-platedepending from the hood in line with the outlet of the blowpipe, thesaid plate causing the flame to rebound, substantially as open at oneend and at the top, and a deflec-
